Cree's XLamp CXA2 high-density LEDs double lumen output

Cree Inc of Durham, NC, USA has launched the XLamp CXB1310 and CXB1520 high-density LED arrays. Incorporating elements of the firm's SC5 Technology Platform, the new LEDs deliver the highest lumen density at 6mm and 9mm – claimed to be the most lumens in the industry for their LES [light emitting surface] sizes. The advance enables new LED lighting form factors for applications such as track lights, lamps and downlights, says the firm. For example, the CXB1520 LED packs the lumen output of seven 60W-replacement lamps into an area much smaller than a dime, allowing lighting manufacturers to put more light where it is intended at a lower system cost.

The high performance of the CXA2 high-density LED arrays allow lighting manufacturers to reduce thermal, mechanical and optical costs at the system level. For example, when combined with a 74mm-diameter optic, the 3000K, 80CRI CXB1520 high-density LED array delivers over 50,000 candela in a 10° beam while drawing only 40W. This high lumen density allows lighting manufacturers to deliver the performance of a 70W ceramic metal halide (CMH) PAR38 lamp through a much smaller PAR20-size optic using 43% less power. The CXB1310 high-density LED array delivers up to 3200 lumens in a 6mm LES, allowing similar reductions in size and power from traditional light sources.

Offering what is claimed to be the industry's best color consistency for designs that use only one LED, XLamp CXA2 high-density LED arrays are characterized and binned at 85°C, available in 2-, 3- and 5-step EasyWhite color temperatures (2700–6500K) and correlted color temperature (CRI) options of 70, 80 and 90. The CXB1310 and CXB1520 LEDs have LM-80 long-term test data available immediately, delivering reported L90 lifetime projections of at least 36,300 hours at 85°C and 105°C.

The CXA2 high-density LED arrays are available in the same form factor as the CXA LED arrays, allowing the use of existing optics, holders and drivers. The CXA2 high-density LED arrays are also UL-recognized and feature a level 4 rating. Product samples are available now, and production quantities are available with standard lead times.
